The Nuclear Regulatory Commission (NRC) now mandates the use of data diodes and many other sectors, in addition to electrical and nuclear, also use data diodes effectively. [1] In Europe, regulators and operators of several safety-critical systems started recommending and implementing regulations on the use of unidirectional gateways. [6]

Tunnel diodes and Gunn diodes are examples of components that have negative resistance. Hysteresis vs single-valued: Devices which have hysteresis; that is, in which the current–voltage relation depends not only on the present applied input but also on the past history of inputs, have I–V curves consisting of families of closed loops. Each ...
That part of a computer system devoted to exporting and importing data, for example, in human-readable form. inrush current The transient current that flows when first connecting a device to a power source. Institute of Electrical and Electronics Engineers (IEEE) The American-based society for electrotechnology. Institution of Engineering and ...
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
Also called CLDs, constant-current diodes, diode-connected transistors, or current-regulating diodes. Crystal rectifiers or crystal diodes These are point-contact diodes. [27] The 1N21 series and others are used in mixer and detector applications in radar and microwave receivers. [24] [25] [26] The 1N34A is another example of a crystal diode. [38]
